Written by provocative_envy. A shattered Time-Turner throws Hermione Granger fifty-two years into the past, into 1944 Hogwarts and a lie that makes her Albus Dumbledore's French niece. Stranded in Slytherin, surrounded by boys who will become monsters and legends, she catches the attention of Head Boy Tom Riddle. What begins as survival becomes obsession, mystery, and a dangerous romance with a boy whose charm is already sharpened into a weapon.
